OTTO KRAUS, OF NEIV YORK, N. Y.

SEAT-POST AND HANDLE-BAR FA STENER.

SPECIFICATION forming part of Letters Patent No. 595,179, dated December 7, 1897.

Application filed July 11, 1896.

To all whom it may concern:

Be it known that I, OTTO KRAUS, a citizen of the United States of America, and a resident of New York, in the county and State of New York, have invented certain new and useful Improvements in Seat-Posts and Handle-Bar Fasteners, of which the following is a specification.

My invention has reference to improvements in fastening-s for saddle-posts for bicycles and other velocipedes, and has for its object to provide means whereby the saddlepost or other support is securely held, while its height can be readily adjusted.

lVith this object in view my invention consists, essentially, in the combination, with a tubular member, of a post movably fittinginto said member and a wedging-piece extending through the member and the post and adapted to engage with the post to lock the same.

The nature of my invention will best be understood when described in connection with the accompanying drawings, in which- Figure 1 represents an elevation of a portion of a velocipede provided with my improved fastening device as adapted for the saddle-post. Fig. 2 is a bottom view of the same. Fig. 3 is a perspective View of the wedging-piece.

Similar letters and numerals of reference designate corresponding parts throughout the several views of the drawings.

Referring to the drawings, the letter A designates the diagonal tubular member of a diamond frame of the usual construction. Into said member is fitted the post B of the saddle-support C, said post being tubular, as usual.

In carrying out my invention I provide the post 13 with a longitudinal slot 1 and the tubular member A with an opening or passage 2 near its upper end, placed in the line of the slot 1.

D is the wedging piece, composed of a tongue 3, lying within the post B, and a part I, bent substantially at right angles thereto and forming a handle for said wedging-piece. In the present example I have made the said wedging piece substantially elliptical in shape, with the major axis somewhat greater than the internal diameter of the post 13, while the minor axis is substantially equal in Serial No. 598,853. (No model.)

length to the said diameter of the post B. The wedging-piece can be inserted into the tubular member A by slipping the same, with the elliptical portion foremost, down into the tube A and then passing the handle 4 upwardly through the passage 2 in the member A, or by making the slot and passage wide enough to turn the wedging-piece the latter can be inserted directly. The wedging-pieoe, it will be noticed, can turn in the memberA as an axis. A spring 5 may be attached to the inner portion of the wedging-piece,which spring holds the same upwardly, substantially as shown in Fig. 1,.and ol'l'ers resistance to displacement, thereby preventing overbalancin g when the saddle-post is removed.

It is now evident that when the saddlepost is inserted into the member-A, While the Wedging-piece is held in an oblique position with respect to the diameter of the tube by pressing on the handle I, the saddle-post B can be slipped into the member A a distance to correspond to the required height of the saddle. When, however, the handle at is released and the rider mounts the saddle, the wedging-piece D immediately grips thesaddle-post and tends to expand the same, and as it cannot follow the motion of the post it retains the same positively in the position to which it had been adjusted. In the present instance I have shown the usual reinforcement E at the juncture of the several tubes, Which reinforcement is perforated at (3 for the passage of the wedging-piece.

It is of course to be understood that the fastening device may equally Well be applied to handle-bars and other supports and that any optional shape could be given to the same so long as its length exceeds that of the interior diameter of the tubular post.

It will be readily understood that by the above-described fastener the saddle or handle-bar is always held in line with the frame, while at the same time its height can be very quickly adjusted.

What I claim as new is-- 1. A support for saddle and like posts, comprising a tubular post, a tubular member receiving said post, and a wedging-piece placed within the said post and provided with an arm or handle extending exterior to the til bular member; said piece being of greater length than the distance across the corresponding portion of the post and supported by the tubular member, substantially as described.

2. A support for saddle and like posts, comprising a tubular post, a tubular member receiving said post, a Wedging-piece placed within the said post and provided With an arm or handle extending exterior. to the tubular member; said piece being of greater length than the distance across the corresponding portion of the post and supported by the tubular member, and a spring acting on the Wedging-piece for pressing the same upwardly, substantially as described.

3. Asupport for saddle and like posts, com- OTTO KRAUS.
